Ответ:

${9}^{2} + 19 =9 \times 9 + 19 = 81 + 19 = 100 \\ \\ {17}^{2} - 209 =17 \times 17 - 209 = 289 - 209 = 80 \\ \\ {6}^{3} \div 3 = (6 \times 6 \times 6) \div 3 = 216 \div 3 = 72 \\\\ {2}^{3} \times {3}^{2} =(2 \times 2 \times 2) \times (3 \times 3) = 8 \times 9 = 72 \\ \\ {(15 - 7)}^{2} \div {2}^{3} = {8}^{2} \div 8 = {8}^{2 - 1} = 8 \\ \\ {(17 - 16)}^{8} + {2}^{5} = {1}^{8} + 32 = 33 \\ \\ {10}^{6} - {20}^{4} = (10 \times 10 \times 10 \times 10 \times 10 \times 10) - (20 \times 20 \times 20 \times 20) = \\ {10}^{3} \times {10}^{3} - {20}^{2} \times {20}^{2} = 1000 \times 1000 - 400 \times 400 \\ 1000000 - 160000 = 840000 = 84 \times {10}^{4} \\ \\ {3}^{4} \times {10}^{4} =( 3 \times 3 \times 3 \times 3) \times (10 \times 10 \times 10 \times 10) = {3}^{2} \times {3}^{2} \times {10}^{2} \times {10}^{2} = \\ 9 \times 9 \times 100 \times 100 = 81 \times 10000 = 810000 \\ \\ {5}^{4} \div {5}^{2} = {5}^{4 - 2} = {5}^{2} = 5 \times 5 = 25$
